Answer:
Average 3am - 9am: [tex]\frac{5}{6}[/tex]
Average 9pm - 3am: [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Average Rate of Change: [tex]\frac{f(b)-f(a)}{b-a}[/tex]
Step 1: Define coordinates
3am - 9am; (3, -3) and (9, 2)
9pm - 3am; (9, 0) and (3, -3)
Step 2: Find rate of change
[tex]\frac{2-(-3)}{9-3}=\frac{2+3}{6} =\frac{5}{6}[/tex]
[tex]\frac{-3-0}{3-9}=\frac{-3}{-6} =\frac{1}{2}[/tex]
